So, Microsoft finally released it for retail. It will pop-up soon in your windows update thing.
I’ve installed it a month ago and it is really satisfying.

NOTE: if you are using a pirated or cracked version of Vista, this update will detect it, and deactivate your windows. Microsoft somehow perfected their anti-piracy algorithms. However, unlike in XP, an unactivated version of Vista will not be put into a reduced function state. So far, the only annoyance for me is that every 30 minutes or so, my desktop background changes to solid black, besides that, I don’t see any difference between a pre and a un activated Vista.
Sorry Versatile1 for posting over your thing, and thanks for inserting a picture!
